Refine
Offline AI grammar checker for Mac
Refine is a macOS writing assistant that checks grammar and fluency, rewrites and translates text, and explains its suggestions inside the apps you already use. Its default models run locally on your Mac, so after a one-time model download, checks work offline and text is not sent to a server. You can also connect your own API key for cloud models (OpenAI, Anthropic, Gemini, OpenRouter, Bedrock, Ollama, LM Studio). It is built and maintained by one independent developer and funded by users rather than advertisers or investors.
